Patent CA-2118803-A1 (CA)
Title: Mobile communications device registration method
Inventor: TIEDEMANN EDWARD G JR
IPC: H04M11/00
Filed: 1992-09-18
Abstract: A distance based method for mobile station registration in a cellular communication system. The mobile station (10) regis-ters whenever it moves into a new cell (C2) that is greater than some predefined distance from the previous cell (C1) where it re-gistered. Cell base stations (12) transmit corresponding base station location information and a distance value. The mobile station (10) receives the base station location information and computes the distance (18) from a cell (C1) in which the mobile station last registered to the current cell (C2) in which the mobile station is present.  When the computed distance is greater than the distance value associated with the registration cell the mobile station registers.  Pages for the mobile station (10) are transmitted within a group of cells (16, 20) within a distance of the registration cell corresponding to the registration cell transmitted distance value.

Abstract: The pallet container (1) for liquids has an exchangeable inner container (2) made of sheet metal, an outer casing (6) of latticework and a pallet (9) which is designed as a bottom tray (10) and receives the bottom (16), designed as a drainage bottom, of the inner container in a positive-locking manner. The inner container (2) of sheet metal, preferably of dual-walled design, is welded together from a casing (11), a bottom part (12) and a lid (13). To produce the inner container, a rectangular sheet-metal blank is bent to form a tubular body whose abutting edges are welded longitudinally. The tubular body is stretched to form a casing of rectangular cross-section. A circumferential bead with a V-shaped cross-section is then moulded in each case into the two end regions of the casing with spacing from its edges which are subsequently trimmed. The deep-drawn, tray-shaped bottom part is then fitted precisely with a bent edge onto or attached to the outer flank of the one bead of the casing, and the bottom part is fixed to the casing. The lid is mounted on the casing in the same manner. The bottom part and the lid are welded to the casing. To form a smooth transition between the casing and bottom part on the one hand and the casing and lid on the other hand, the transition regions between the casing and the bottom part and the casing and the lid are widened by applying pressure to the inner container inserted in a supporting mould. <IMAGE>

Title: Use of acid-stage filtrate in cooking liquor preparation
Inventor: LINDBERG HANS G
IPC: D21C7/14
Filed: 1996-03-12
Abstract: Acidic bleach plant effluents from a cellulose pulp mill utilizing a sodium-based cooking process are effectively utilized without contamination of pulp mill processes with undesirable metal ions. The bleach plant effluent, in the form of filtrate, is treated with an alkaline stream to precipitate solids containingmetals from the filtrate, producing a reduced metal content filtrate. The reduced metal content filtrate is used to wash or dilute lime mud which is in turn used to produce lime for causticizing green liquor to produce white liquor.Acid filtrate which is not treated to remove metals may be used to dissolve smelt from the recovery boiler to make green liquor which is clarified to produce clarified green liquor and dregs containing metals. The alkaline stream used to precipitate solids from the acidic filtrate is preferably clarified green liquor or white liquor, although an alkaline filtrate from an alkaline bleaching or delignification stage may be used.
